5-Hydroxyindole-3-acetic acid is the main metabolite of serotonin or metanephrines, which can be used as a biomarker of neuroendocrine tumors.
5-Hydroxyindole-3-acetic acid (5HIAA) is a metabolite issued from serotonin metabolism, and the latter is synthetized from the essential amino acid tryptophan. Serotonin is mainly metabolised by monoamine oxidase in the liver and the lungs[1].
